KIM SOO HYUN/SONG SAM DONG

Song Sam Dong is a country bumpkin who follows Hye Mi to Seoul. He originally didn't want to go since he really loves his mother and doesn't originally want to leave her to come to Kirin High School. He is a musical genius, but he is naive and has a hearing problem. Sam Dong is in love with Hye Mi and he defends her when her schoolmates turn on her, but starts to regret all that he has done for her when he realizes Hye Mi has feelings for Jin Guk. Hyemi gives him a make over where he transforms into a "hottie" and he gets a haircut that resembles Jin Guk's. He eventually become a famous singer.
